I Application filed June 22,

My. invention relates to improvements in vehicle jacks of the oscillatory lever type particularly to a novel and improved operating attachment therefor.

Now that low underslung automobile bodhandle can be used in the socket of the oscil latory lever owing to the lack of clearance and the operator has to manipulate the same from a very cramped prone or crouching position. m

It is therefore the primary object of my invention to provide a novel and improved operating attachment which can be quickly attached to any type of oscillatory lever jack, and which will enable the operator to a readily place the jack in p ositionand manipulat'e it from a point well clear of the car.

Further, the invention comprehends a novel attachment of this class whereby the oscillatory operating lever of the jack is operated by a semi-rotary. lever;

It is also. an ob ectof the invention to provide a device as set forth which willbe very simple and durable in constructlon,

highly eliicient and convenient in operation ancLwhich will be relatively inexpensive of manufacture.

With the foregoing and other objects in view the invention comprises a novel combination and arrangement of parts to be hereinafter described and claimed,- and in order that the same may be better understood, reference should be had to the accompanying drawings forming a part of this specification. It is understood, of course, that I do not propose to limit myself to the precise structural arrangement shown and described, but reserve the right to make such changes and modifications therein as fairly fall within the spirit and scope of the invention as claimed.

Inthe drawings,

and showing the jack shank in section; and, igure 3 is a group perspective view showing certain of the'elements of the attachment in disassembled relation.

Referring specifically to the drawing in which like parts are designated by siii'iilai" reference characters throughout, numeral denotes a jack having an oscillatory operatinglever 5 ofsocketed form for the recep-. tion of a handle; Since the jack, as already stated, of familiartype and, per se, forms no part of" the present invention it need not i be described. My attachment comprises a pair of clamp ing plates 6 and 7 bolted together as indicated at 8 and 9 whereby to embrace the jack standard asclearly shown'in Figs 1 and 2. The plate has an offset portion 7 forming a space which the jack standard 7 may be inserted. By preference, I use spacer sleeves 9 between the plate 6 and the offset 7 of plate 7 through which the bolts 9. pass. l hese prevent the plates 6 and 7 from baring buckled and also protect the bolts 9.

The outer side of the plate 6 is foriuyd" with a longitudinally disposed bearing 10 for the end of ashort shaft 12 on Which is keyed or otherwise rigidly fastened a socketed member 13 having a medial bifur cated crank arm 14-. 12 and 13 may be integral if desired. The forward end of the socket member 13 delines a shoulder to bear against the proximate end of bearing 10, and end thrust of the shaft 12 is prevented by a nut and washer 16, 17 upon the end thereof incontact with the other end of the bearing 10..

An operative connection between the bifurcated crank arm 14 and the socketed jack9 The other end of the lever 22 is T-headed 105 at 2d and carries the laterally extending hanc grip rod 9.5 as shown.

It is manifest that with this attachment the jack 4 can be readily inserted under an axle and from a point clear of the car body. 110.

Oscillation of the socketed jack lever 5 to elevate the wheel will be conveniently accom- Of coure the elements plished in a self-evident manner through elements 13, 14c, 18 and 21 upon short rotary oscillation of hand grips 25.

From the foregoing description read in connection with the accompanying drawing the advantages, conveniences and economies of my attachment, from both the manufacturers and users point of view, will be readily appreciated by those skilled in the art.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is 1. The combination with a jack having an oscillatory actuating lever; of a bearing member, means for clamping the bearing member to the jack, a shaft rotatably carried in said bearing, a crank fixedly carried by said shaft and a link connection between said crank and said oscillatory jack operating lever whereby said actuating lever will be oscillated upon partial rotations of said shaft.

2. The combination with a jack having an oscillatory operating handle; of a pair of clamping plates defining an intermediate recess for the jack standard, means for clamping said plates upon said standard, a bearing formed upon one of said plates, a shaft rotatably carried in said bearing, a crank fixedly carried by said shaft, and a connection between said crank and said oscillatory actuating lever whereby said actuating lever will be oscillated upon partial rotations of said shaft.

3. The combination with a jackhaving an oscillatory actuating lever; of a bearing member, means for clamping the bearing member to the jack, a crank member swingingly carried by said bearing member and movable in a plane substantially transverse with respect to the plane of movement of said actuating member, and a connection be tween said crank and said oscillatory actuating lever. 7

l. The combination with a jack having an oscillatory actuating lever; of 'a bearing member, means for clamping the bearing member to the jack, a crank member swingingly carried by said bearing member and movable in a plane substantially transverse with respect to the plane of movement of said actuating member, and a pivotal link connection between said crank and said OSClllatory actuating lever.

5. The combination with jack having an oscillatory actuating lever; of an operating lever therefor, means for mounting said second lever for oscillatory movement in a plane substantially at ri ht angles to the plane of said actuating lever, and an operative con nection between the two levers.

6. An operating attachment for oscillatory lever jacks comprising a clamp including a pair of clamping plates having means for attachment to the standard of the jack, the inaj or portions of said plates flatly engaging each other and projecting from said standard to a point approximately beneath the operating lever of the jack, a bearing carried by one of said plates and lying in a plane approximately at right angles to the pivot point of said oscillatory jack lever, a shaft in said bearing, a lateral crank carried by said shaft and movable in a plane substantially at right angles to the plane of movement of said jack lever, a connection between said crank and said jack lever, and means for oscillating said crank.

7. An operating attachment for oscillatory lever jacks comprising a clamp including a pair of clamping plates having means for attachment to the standard of the jack, the major portions of said plates flatly engaging each other and projecting from said standard to a point approximately beneath the operatinglever of the ack, a bearing carried by one of said plates and lying in a plane approximately at right angles to the pivot point of said oscillatory jack lever, a shaft in said bearing, a socketed enlargement formed at one end of said shaft and forming a shoulder for engagement with one end of said bearing, a lateral crank carried by said shaft and movable in a plane substantially at right angles to the plane of movement of said jack lever, a connection between said crank and said jacklever, and an operating rod engageable in the socketed member for oscillating said shaft and crank member for actuating said oscillatory jack lever.

In testimony whereof I afi'ix my signature.
